TALK=T;RUN(1,1) DISPLAY ---------------------------------------------------------- This case concerns axisymmetric incompressible laminar (or turbulent LTURB= T) flow in the pipe with linear expansion. The flow exhibits recirculation in the region on the pipe axis. That kind of flows is common for gas burners. The problem is set in Y-Z plane; the swirling velocity component UC1 is solved as scalar using special treatment (LSG6= T). User can model the same problem as 3D (NX>1), however the speed of convergence, provided the problem is truly axisymmetric, is rather slow. User can switch from the default colocated computational algorithm (CCM) to the staggered one (STAG) by setting LCCM= F. ---------------------------------------------------------- ENDDIS PHOTON USE p ; ; ; ; ; msg Computational Domain: gr i 1 msg Press Any Key to Continue... pause cl set vec av off msg Velocity Vectors: vec i 1 sh msg Press Any Key to Continue... pause cl msg Contours of Pressure: con p1 i 1 fi;0.005 msg Press Eto exit PHOTON ...
